The basic optical, thermally-stimulated luminescence (TSL) and optically-stimulated luminescence (OSL) properties of Tl-doped RbBr transparent ceramics synthesized by the spark plasma sintering were investigated. All the samples were transparent in the visible range. As the photoluminescence, TSL and OSL spectra, two emission bands around 380 and 520 nm were observed in all the prepared samples. The emissions around 380 and 520 nm would be attributed to the ³P₁→¹S₀ transitions of Tl⁺ and off-center type of self-trapped exciton perturbed by the Tl⁺, respectively. As the OSL dose response functions, the sensitivity was confirmed to be as low as 1 mGy in the 0.5, 1.0 and 3.0% Tl-doped RbBr transparent ceramics. Using OSL of Tl-doped RbBr transparent ceramics, we have successfully obtained an X-ray imaging of the operational amplifier.

研究了通过火花等离子体烧结合成的掺Tl的RbBr透明陶瓷的基本光学，热激发发光（TSL）和光学激发发光（OSL）特性。所有样品在可见光范围内都是透明的。作为光致发光，TSL和OSL光谱，在所有制备的样品中均观察到380和520 nm附近的两个发射带。380和520 nm附近的发射将归因于Tl ⁺的³ P ₁ → ¹ S ₀跃迁和受Tl ⁺干扰的偏心型自陷激子。， 分别。由于OSL剂量响应功能，在0.5、1.0和3.0％的掺T1的RbBr透明陶瓷中，灵敏度可低至1 mGy。使用掺Tl的RbBr透明陶瓷的OSL，我们已经成功地获得了运算放大器的X射线成像。
